After looking at the code in descrobject.c, I *think* a method-wrapper is  
used to create a Python object out of internal methods (stored as C  
function pointers in the type structure), as if they were actual Python  
methods.
That is, they wrap an internal function pointer (defined in the type)  
along with a Python object ("self"), so it can be used in Python code as  
it were a normal instance method. But certainly I can be wrong...
